    摘要:

    充分探究城市能源代谢过程中部门间的内在差异,深入解析并评估其对城市能源代谢过程的影响对于进一步优化城市能源代谢结构,推动节能减排、提质增效具有重要价值。本文基于引力模型分析城市能源代谢过程中能源流两端连接节点的属性差异,选取煤、石油、天然气三种能源,以北京市非首都功能疏解部门为例探究要素差异及部门自身属性差异在能源代谢过程中的影响;利用情景分析法,分析两种能源优化强度和三种部门疏解强度的6种组合情景下四部门的不同种类能源消耗的变化。结果表明,不同要素对部门能源消耗的正负反馈机制以及不同部门对不同能源偏好程度均存在异质性,这种异质性导致不同政策情景对北京市非首都功能疏解部门能源结构优化的作用效果不同。强优化强疏解情景对于制造业部门煤和天然气能源的替代最为有利,低疏解强优化情景对控制交通业及批发和零售业部门的能源消费,改善教育业的能源消费结构最有利。

    Abstract:

    The promotion on energy conservation and efficiency improvement relies on the comprehensive understanding of the urban energy metabolic mechanism, especially of the impacts related to heterogeneity within the urban energy metabolic processes. In this paper, the gravity model is introduced to analyze the attribute differences of the connecting nodes on each side of the energy flows within urban energy metabolic processes. Using Beijing’s main departments associated with the non-capital functional dispersal policies as the case study, three fossil energy including coal, oil and natural gas are included in the empirical analysis to evaluate the induced impacts within Beijing’s energy metabolism due to the heterogeneity of departments. Based on the scenario analysis that consists of six combinations of two intensities of energy optimization and three intensities of department dissolution, results suggest that both the positive and negative feedback mechanisms of different factors on the departments’ energy consumption and the degree of preference for different energy in different departments are heterogeneous. The heterogeneity causes different policy scenarios to have different effects on the optimization of the energy structure of Beijing''s non-capital functional demobilization sector. Strong optimization and strong dissolution scenarios are most beneficial to the substitution of coal and natural gas in the manufacturing department, while low dissolution but strong optimization scenarios are most beneficial to control energy consumption in the transportation industry, wholesale and retail departments. The latter also has some advantages on improving the energy consumption structure of the education industry.
